When Overexertion Pushes You Into a Flare

Why pacing protects your body before symptoms appear.

For people with autoimmune disease, “too much activity” is not laziness—it’s biology. The Lupus Foundation lists overexertion as a leading flare trigger

 

What’s happening

Inflammation increases when your system exceeds its energy threshold. The problem is not the task itself—it’s the cumulative load.

 

What you can do

  • Break tasks into micro-chunks.
  • Add recovery periods before exhaustion appears.
  • Use “body budgeting”: predict how much energy each activity will cost.
  • Pre-plan low-energy alternatives.

 

What to avoid

  • Using rest as a reward instead of a tool.
  • Ignoring early stiffness, overheating, or brain fog.

 

How to move forward

Pacing is not weakness—it’s strategic energy management that prevents flares and the medical costs that follow.
